Casper's two latest experiments are not more decisive; the fact that ferrocyanide of potassium is found in the contents of the bladder after it has been introduced into the posterior portion of the urethra, and that its existence can be proved with the well-known reaction with iron, is by no means conclusive; pressure caused by instillation could easily force a small quantity of the solution into the bladder, capable of being discovered, thanks to the excessive sensibility of the reaction with ferric ferrocyanide. Finally, the presence of gonococci in the posterior part of the urethra cannot be considered a " proof" in favour of this theory. We quite recognise the difficulties of determining the exact localization of gonorrhoea in the urethra, even with the aid of the endoscope, and we are convinced that the views we have just discussed can no more be relied upon than those put forward in favour of Guyon's theory. We agree, however, with Leprivost, Zeissl, Mracek, and others, that posterior urethritis does not lead to clouding of the urine contained in the bladder, and that this can only take place when paralysis of the sphincter of the bladder is present, so that if the second portion of urine contains pus, it must be considered to be of cystitic origin, a fact which Guyon opposes less than one would expect, after what has been said by his followers. Lesser, also, now admits that in posterior urethritis the second portion of urine may be clear, a phenomenon which he explains by the fact that the pus has " not yet" entered the bladder. As we have already remarked, the non liquet with which we bring...
